Francisella tularensis is an aerobic, Gram-negative, non-motile and non-sporing
Coccobacillus which is the causative agent of the disease Tularemia, an infectious disease
which is highly virulent in humans and rabbits. F. tularensis has a DNA genome of almost
1.9M nt in length arranged in a circular conformation and encoding under 2000 genes.
There are several subspecies of this bacterium which vary in their degree of virulence. The
highly virulent Francisella tularensis Type A strain is found mainly in North America
whereas the less virulent F. tularensis palaeartica Type B strain is found in Europe and
Eurasia. Two other non-virulent strains are less well studied and found in central Asia.
This bacterium uses arthropods as vectors to infect humans and animals but can also be
transmitted via the air. Infection occurs via the mucosal membranes of the lung and
gastrointestinal tract and also through the skin using its type 4 pili to adhere to the host
cells. From here it targets organs including the lymph nodes, liver, spleen and lungs.
Within the host, the bacterium infects macrophages by phagocytosis and multiplies until
the host cell bursts open, releasing bacteria to infect other cells.
Infection with this bacterium results in a debilitating disease even at low levels of infection.
Symptoms may vary depending on the mode of infection with the most common type of
infection via insect bite causing an ulcer at the bite site accompanied by fever, chills,
headache and fatigue. Infection via inhalation causes a typhoidal disease with fever,
fatigue, weight loss and pneumonia. There is no vaccine available against this bacterium
with most cases of infection being treated with antibiotics.
